[QUOTE="65WSM, post: 1382432, member: 9551"] Again Hodgdon 100V is a poor choice of powders. Why put a .260 Remington powder charge (?54 grains?) in a 6.5-280 Ackley? Magnum primers will never promote accuracy. That is why Lapua brought out small primer pocket cases for the 6.5 Creedmore. Here is what Quickload shows for 130gr (I have a 9 twist barrel) Berger VLDs that actually use the case volume. Alliant Reloder-26 63.70gr 94 %fill 3,251fps 62,000psi Norma MRP 62.34 95 3,229 61,185 Vihtavuori N560 61.04 95 3,174 57,559 Accurate MAGPRO 63.51 95 3,153 56,800 Ramshot Magnum 65.06 95 3,113 56,430 Accurate 3100 59.74 95 3,034 56,585 Norma MRP 2 59.74 95 2,918 43,867 Hodgdon H1000 59.09 95 2,850 42,128 Hodgdon Retumbo 60.06 95 2,806 37,744 [/QUOTE]
